The Ochterus of the Australian region are revised. Following species are described as new: Ochterus occidentalis sp. n., O. nigrinus sp. n., O. bacchusi sp. n., O. kokodae sp. n., O. monteitheorum sp. n., O. paucistriata sp. n., O. louisiadae sp. n., O. alticola sp. n., O. cheesmannae sp. n., and O. latior sp. n. O. pseudosecundus Baehr is ranked a subspecies of O. secundus Kormilev. For O. australicus Jaczewski a lectotype is designated. O. dufourii (Montrouzier) is completely, most other species are partly redescribed. Analysis of distribution shows a surprising high number of species in Australia and New Guinea, compared with the whole Oriental region, as well as the large South Asiatic Islands. The possible reasons for this richness are discussed. A detailed analysis, however, must await a thorough revision of the Oriental and African Ochterid fauna.
